This edited text offers a thorough description of cytochemical and ultrastructural characteristics for a wide variety of leukemic conditions. The text is well organized, extremely well illustrated, and up-to-date. The index is excellent.

The various authors have correlated well their discussions of cytological findings with immunologic diagnosis. The book does not contain a separate section on the application of immunologic techniques to ultrastructural analysis.

The text is organized in disease units. It does not, however, include a single systematic review of the acute nonlymphoblastic leukemias, so as to make access to that body of information easy to obtain. On the other hand, there are outstanding descriptions of the other forms of leukemia, including the secondary leukemias, blast transformations, the acute lymphoblastic leukemias, prolymphoblastic leukemia, hairy-cell leukemia, megakaryocytic leukemia, and plasma cell and other leukemia.
